hectárea

Hectárea is a unit of area in the metric system, commonly used to measure land. It is derived from the prefix "hecto" meaning one hundred, and "are," which is a unit of area equal to 100 square meters. Therefore, one hectárea is equivalent to 10,000 square meters. This is also equal to 100 ares. Another common comparison is to the acre, an imperial unit of area. One hectárea is approximately 2.471 acres.

The hectárea is widely used in agriculture, forestry, and land surveying across the world. Its convenient size makes it suitable for measuring farms, forests, and other large land parcels. For instance, a typical agricultural field might be measured in hectáreas. In terms of dimensions, a hectárea can be visualized as a square with sides of approximately 100 meters, or as a rectangle measuring 200 meters by 50 meters. The definition of the hectárea is standardized internationally as part of the International System of Units (SI).
